ROBERT H. BOWLING, OF NEWARK, OHIO, ASSIGNOB OF ONE-HALF TO BENJAMIN B. LOAR, OF SAME PLAGE.

WHISTLE FOR CABINET AND PIPE ORGANS.

SPECIFICATION forming part of Letters Patent No. 249,322, dated November 8, 1881.

Application filed May 3, 1881.

To all whom it may concern:

Be itknown that I, ROBERT H. DoWLINe, of Newark, in the county of Licking and State of Ohio, have invented certain new and useful Improvements in Whistles for Cabinet and'for Pipe Organs; and I do hereby declare the i'ollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to Whichit appertains to make and use it, reference being had to the accompanying drawings, which form part ot' this specification.

My invention relates to improvements in Whistles for cabinet and for ypipe organs.

The object of my invention is to do away with the hissing sound in pipe-organs resulting from the pressure in any great degree upon the bellows, and also to do away with the blowing-bellows in cabinet or reed organs, by substituting in a pipe-organ a whistle or pipe, the musical sound of which is produced by an exhaust-bellows, and substituting in cabinetorgans a like Whistle, the sound being produced by the suction-bellows. The tone resulting from this suction-whistle is much smoother and will blend more harmoniously than that arising from the blow-Whistle now in use.

My whistle or pipe herein described maybe constructed of any metal or material, and may be either round or square in form.

Figure l represents my invention as applied Fig. 2 is a sectional view ot' my invention as applied to cabinet-organs. Fig. 4 is a sectional view of my invention. Fig. 3 is a view ot' under side of part B. Fig. 5 is an inside view of A. Fig. 6 is a view of A at the end opposite to which suction is applied. Fig. 7 is a view of B at that end Which forms a tongue, the tongue being formed by B being beveled, as shown in Fig. 4.

It will be seen that A, Figs. 5 and 6, is rabbeted or channeled on the inside face, and that part B has a beveled tongue upon the under (Model.)

side. The upper face ot' B is smooth. The pieces A and B are of the same width, and when said two pieces are placed together th ere is an air chamber or passage. formed-viz., by said channel or rabbet in A, the tongue upon B being underneath and at the end opposite to which suction is applied. Suction is applied at that part marked E.

O, Fig. 1, is the pipe, to which myinvention is attached in pipe-organs by closing the end ofthe pipe to which the whistle is to be attached, leaving a small opening in the side of the pipe, as indicated by the dark lines in O, Fig. 1. Over this opening rests the beveledtongue at the end of B, leaving still a small part of the opening in the pipe uncovered, as seen by reference to Fig. 2.

In cabinet or reed organs my invention is attached to the end of the pipe in the manner indicated in Fig. 2.

` The tone is regulated the same as the tone ot' pipe-organs and Whistles in cabinetor reed 0rgans is now regulated-viz., by the timingslide D sliding in the pipe O, as shown in Figs. 1 and 2', and therefore I do not claim such method ot' tuning as part ot' my invention; but

What I do claim, and desire to secure by Letters Patent, is-

An organ-Whistle having a mouth-piece consisting of the channeled piece A, in combination with the piece B, having the beveled tongue, and arranged at the side or end of the pipe in the manner described above, whereby the pipe is adapted to produce tones by having the air drawn through it by an exhaustbellows.

In testimony whereof I have hereunto suhscribed my name in the presence ot two witnesses.

ROBERT H. noWLrNe.
